Abstract
Description
Technical Field
[0001] This invention relates to the field of alarm device technology, specifically to a safety interlock alarm device and method for construction safety hazards. Background Technology
[0002] During various construction projects, there are some safety hazards that need to be identified and alerted by alarm devices. For example, during trench excavation, although horizontal support plates are installed to support and protect the sides of the trench, support failure can still occur, leading to accidents. Therefore, alarm devices are needed to provide early warnings before such accidents happen.
[0003] In the early stages of potential hazards, when the crossbeams experience lateral displacement due to increased soil pressure, disengagement of interlocking joints, or foundation settlement, the support becomes unstable and gradually worsens over time. However, existing trench construction lacks real-time alarm equipment, and small displacements in the early stages are difficult to detect in noisy construction environments. When an accident occurs, workers cannot quickly become alert and evacuate from the trench, posing a significant safety hazard. Summary of the Invention

[0014] To better achieve the objectives of this invention, this invention also provides a safety interlock alarm method for addressing construction safety hazards, comprising the following steps: S1: In the absence of safety hazards, the protective frame is on the first assembly plate and the ladder is on the second assembly plate, with the channel between the base plates flowing, allowing workers to carry out normal construction. S2: When a safety hazard occurs in the substrate area, the triggering mechanism detects substrate displacement, the protective frame in that area is lowered, and the alarm light and buzzer in that area are activated to sound an alarm. At the same time, the ladder on the substrate on the side adjacent to the danger area is released. S3: If a safety hazard occurs in only a single area, after the worker falls out of the danger zone, he or she will evacuate from the trench through a ladder lowered from a nearby safe area, and personnel will be organized to investigate the hazard. If multiple interconnected areas have safety hazards, proceed to step S4. If a large area has safety hazards, proceed to step S5. S4: The alarms, safety frames, and ladders in step S2 are triggered in succession. Workers must follow the prompts of alarm lights and buzzers, cross the chain of danger zones, move to the nearest safe zone, evacuate via the ladder, and organize personnel to investigate potential hazards. S5: The alarm, protective frame and ladder in step S2 are triggered one after another. The worker has no safe area to reach. At this time, the worker needs to select an area with small substrate offset and where the ladder and protective frame are lowered. The worker should then quickly evacuate the trench from the ladder in that area and organize personnel to check for hidden dangers.
[0015] The beneficial effects of this invention are: 1. This invention can sensitively detect small displacements of the support substrate through a triggering mechanism, and automatically trigger the alarm light in the danger zone when the displacement is excessive, so that workers in the area can quickly notice and leave the danger zone in time, avoiding accidents caused by continued construction in the danger zone.
[0016] 2. After the alarm is triggered by the triggering mechanism, the present invention can also automatically provide temporary reinforcement support for the lower protective frame in the dangerous area, so as to prevent the base plate from collapsing immediately in the event of a serious accident. This gives workers in the dangerous area a certain reaction time to evacuate. At the same time, the ladder on the adjacent base plate is lowered, so that workers can quickly evacuate from the trench in the nearest safe area via the ladder, completely get away from the dangerous area of the trench, and avoid accidents.

Then the slider 266 is ejected by the spring, locking the protective frame 22 inside the locking frame 261 so that it cannot be disengaged from the locking groove, thus ensuring the stable support of the protective frame 22.
[0028] Specifically, a transmission rod 321 is provided on the outside of the detection cylinder 32, a fixed platform 36 is provided on the outside of the first assembly plate 21, a fixed top rod 323 passing through the fixed platform 36 is provided at the end of the transmission rod 321, a trigger rod 356 is provided on the outside of the movable platform 35, the trigger rod 356 is in contact with the end of the fixed top rod 323, a reinforcing rod 221 is provided inside the protective frame 22, the reinforcing rod 221 has a first slot 222, and a first locking block 352 that slides along the first slot 222 is provided on the outside of the movable platform 35.

[0031] Furthermore, a pusher 351 is installed on the top of the movable platform 35. The first locking block 352 and the pusher 351 both pass through the first assembly plate 21 and are movably connected to the first assembly plate 21. The first assembly plate 21 has multiple through slots, so that the first locking block 352 and the pusher 351 can both pass through the first assembly plate 21 and slide up and down. Multiple telescopic columns 353 located at the corners are also installed at the bottom of the movable platform 35. Multiple guide cylinders 362 perpendicular to the telescopic columns 353 are also installed on the top of the fixed platform 36. The telescopic columns 353 are inserted into the guide cylinders 362.
[0032] Specifically, a limit plate 322 is installed on the outer wall of the transmission rod 321, a movable opening 361 is opened on the fixed platform 36, a contact switch 354 is installed on the outside of the movable platform 35 on the fixed platform 36, a push button 34 is installed on the outside of the fixed platform 36, the contact switch 354 corresponds to the push button 34, the alarm light 25 and the buzzer alarm 24 are both electrically connected to the contact switch 354, and a buffer pad 355 is also installed on the outside of the movable platform 35.
[0033] Furthermore, a limit plate 322 is installed on the outer wall of the transmission rod 321, and a movable opening 361 is opened on the fixed platform 36. The transmission rod 321 moves within the movable opening 361. The radius of the limit plate 322 is slightly larger than the radius of the movable opening 361. A contact switch 354 is installed at the bottom of the movable platform 35, and a push button 34 is installed at the top of the fixed platform 36. The contact switch 354 and the push button 34 are vertically corresponding. The alarm light 25 and the buzzer alarm 24 are both electrically connected to the contact switch 354. Buffer pads 355 are also installed on both sides of the contact switch 354 at the bottom of the movable platform 35.
[0034] Specifically, the pin 33 passes through the detection cylinder 32 and moves within the detection cylinder 32. A movable disc 324 is also provided on the outside of the detection cylinder 32. A mounting base 31 is provided on the outside of the first assembly plate 21. The mounting base 31 has an annular movable groove 311. The movable disc 324 moves within the annular movable groove 311. A second spring 325 corresponding to the movable disc 324 is provided within the annular movable groove 311.
[0035] Furthermore, the pin 33 passes through the detection cylinder 32 and moves vertically within the detection cylinder 32. A movable disc 324 is also installed on the outer wall of the detection cylinder 32. A mounting base 31 is installed on the outer side of the first assembly plate 21. An annular movable groove 311 is opened inside the mounting base 31. The movable disc 324 can move in any direction in the annular movable groove 311. Multiple second springs 325 arranged in a ring and corresponding to the movable disc 324 are installed in the annular movable groove 311.
[0036] In a safe state, if a safety hazard occurs, the base plate 1 will shift, causing the first assembly plate 21 to shift. The first assembly plate 21 will then cause the movable platform 35 and the fixed platform 36 to shift. At this time, the pin 33 remains inserted in the soil and fixed. As the movable platform 35 and the fixed platform 36 shift with the base plate 1, the positions of the pin 33, the transmission rod 321, and the fixed top rod 323 remain unchanged. However, the relative positions of the fixed top rod 323 and the trigger rod 356 change. If the displacement of the base plate 1 is large, causing the fixed top rod 323 and the trigger rod 356 to shift, the pin 33 and the trigger rod 356 will shift. When the trigger rod 356 is misaligned, the movable platform 35 moves downward and falls. Under the guidance of the telescopic column 353 and the guide cylinder 362, the movable platform 35 moves downward stably. At this time, when the movable platform 35 and the fixed platform 36 are combined, the pressing button 34 contacts the contact switch 354, triggering the contact switch 354. At this time, the buzzer alarm 24 and the alarm light 25 are activated. Workers in the trench can pay attention to the sound and light and stay away from the danger zone. Nearby workers can evacuate through the interlocking evacuation mechanism 4 on the adjacent base plate 1 and safely fall out of the trench. At the same time, when the movable platform 35 falls, it will also cause the first locking block 352 to disengage from the first locking slot 222 on the protective frame 22. As the movable platform 35 continues to move down, the pusher 351 will push the protective frame 22, which has lost the restraint of the first locking block 352, outward. At this time, the protective frame 22 tilts and rotates due to gravity. The end of the protective frame 22 pushes open the slider 266 and enters the locking slot to strengthen the support of the base plate 1 and prevent the groove from collapsing quickly. Example 2, refer to Figures 8-12 This is the second novel embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an interlocking evacuation component, which can extend the evacuable trench ladder 42 in conjunction with the adjacent safe area when supporting and protecting the dangerous area. Specifically, the interlocking evacuation mechanism 4 also includes a lifting guide rail 44 disposed outside the second assembly plate 41 and a sliding guide rail 43 disposed outside the base plate 1. A slide block 45 is disposed outside the lifting guide rail 44. The outer side of the ladder 42 is rotatably connected to the slide block 45 through a shaft hole. A roller corresponding to and engaged with the sliding guide rail 43 is disposed at the end of the ladder 42.
[0037] Furthermore, the interlocking evacuation mechanism 4 also includes a lifting guide rail 44 symmetrically installed on the outside of the second assembly plate 41 and a sliding guide rail 43 symmetrically installed on the bottom outer wall of the base plate 1. The end of the sliding guide rail 43 is in contact with the opposite outer wall of the base plate 1. A slide block 45 is movably connected to the outer wall of the lifting guide rail 44. The outer side of the ladder 42 is rotatably connected to the slide block 45 through a shaft hole. Rollers corresponding to and engaged with the sliding guide rail 43 are symmetrically installed at the end of the ladder 42.
[0038] It should be noted that, under safe conditions, when the climbing ladder 42 is on the second assembly plate 41, there is a gap between the bottom of the climbing ladder 42 and the sliding guide rail 43. When the climbing ladder 42 is lowered, the bottom of the climbing ladder 42 is impacted and then contacts the sliding guide rail 43. The gravitational potential energy generated by the fall gives the slide enough kinetic energy to slide and unfold quickly after it is lowered, which facilitates the escape of personnel. In one implementation, such as Figure 13 As shown, when a safety hazard occurs in a single area, the offset of the dangerous area substrate 1 is detected and triggered, the protective frame 22 of that area falls, and the ladder 42 on the substrate 1 of the adjacent safe area is released, allowing workers to evacuate from the ladder 42 of the adjacent safe area. After ensuring complete safety, personnel are organized to handle and investigate the hazard. In another embodiment, such as Figure 13 As shown, when multiple areas have safety hazards, the danger zones are triggered in a large-scale chain reaction. At this time, since the large-scale danger zones are adjacent, the protective frame 22 is released after the base plate 1 is shifted, and the ladder 42 in the adjacent area is released. The protective frames 22 and ladder 42 that are all lowered in the same area, together with the sliding guide rail 43 at the bottom, form a Z-shaped temporary support and protection frame, which can provide certain support and protection for the shifted base plate 1 that has potential hazards. If there are areas near the worker's location that have not yet shifted, the worker can evacuate from the nearby safe area via ladder 42. After ensuring complete safety, personnel will be organized to handle and eliminate potential hazards. If there is no undisplaced area near the worker's location, attempting to evacuate via the ladder 42 from the safe zone would require traversing multiple danger zones. Furthermore, in severe accidents, a safe zone may not be found, increasing the time spent in the accident trench. In such cases, it is necessary to quickly observe and select an area of the nearby substrate 1 that has been affected by the accident with a smaller displacement. Although this area is still a danger zone, it is still necessary to quickly evacuate from the trench via the ladder 42 in this area. The inclined ladder 42 applies pressure to one side of the substrate 1 through the worker's weight as the worker climbs, temporarily stabilizing it and providing a certain degree of safety for the worker when climbing out of the danger zone via the ladder 42.

The transmission rope 464 passes around the steering shaft 462 and its end is fixed to the center of the top of the movable platform 35.
[0041] In Embodiment 1, after the detection mechanism is triggered, the movable platform 35 descends while pulling the transmission rope 464 downward. The other end of the transmission rope 464, with the steering shaft 462 as the fulcrum, pulls the lifting frame 463 on the other set of base plates 1 on the same side upward. The lifting frame 463 drives the second locking block 465 to move upward and disengage from the second locking slot 422 on the ladder 42. At this time, the ladder 42 loses the limit of the second locking block 465 and falls downward by gravity. The ladder 42 drives the slide 45 to slide downward. When the bottom of the ladder 42 falls onto the sliding guide rail 43, the gravitational potential energy generated by the fall will cause the bottom of the ladder 42 to continue to slide rapidly along the sliding guide rail 43, so that the slide unfolds from a vertical state to an inclined support state. This not only supports the base plate 1, but also improves the support effect when personnel use the ladder 42, allowing workers to safely evacuate from the trench via the ladder 42 and avoid accidents.

A method for using a safety interlock alarm device for construction safety hazards, characterized in that: The device includes a safety interlock alarm for construction safety hazards as described in any one of claims 1 to 9, and the following steps: S1: In the absence of safety hazards, the protective frame is on the first assembly plate and the ladder is on the second assembly plate, with the channel between the base plates flowing, allowing workers to carry out normal construction. S2: When a safety hazard occurs in the substrate area, the triggering mechanism detects substrate displacement, the protective frame in that area is lowered, and the alarm light and buzzer in that area are activated to sound an alarm. At the same time, the ladder on the substrate on the side adjacent to the danger area is released. S3: If a safety hazard occurs in only a single area, after the worker falls out of the danger zone, he or she will evacuate from the trench through a ladder lowered from a nearby safe area, and personnel will be organized to investigate the hazard. If multiple interconnected areas have safety hazards, proceed to step S4. If a large area has safety hazards, proceed to step S5.

Workers must follow the prompts of alarm lights and buzzers, cross the chain of danger zones, move to the nearest safe zone, evacuate via the ladder, and organize personnel to investigate potential hazards. S5: The alarm, protective frame and ladder in step S2 are triggered one after another. The worker has no safe area to reach. At this time, the worker needs to select an area with small substrate offset and where the ladder and protective frame are lowered. The worker should then quickly evacuate the trench from the ladder in that area and organize personnel to check for hidden dangers.
